With the integration of WebRTC codecs and technologies, PowerMedia XMS allows developers to leverage their existing applications to include WebRTC endpoints and media. The flexibility of the XMS solution provides the capability to handle combinations of WebRTC technologies, including audio and video transcoding, DTLS-SRTP security, NAT traversal via ICE or signaling for deployment in virtually any network environment. For example, solution providers can use PowerMedia XMS to handle WebRTC media transcoding, security, and NAT traversal, while using their own WebRTC-to-SIP protocol converter for signaling. Additionally, the support for the Opus audio codec and the VP8 video codec allows XMS to function as a multimedia bridge between WebRTC and IMS networks, providing transcoding between any multimedia parties with VP8 and H.264 up to HD720p resolutions. Because it offers standards-based media control interfaces and management capabilities, XMS can be deployed with a wide range of corresponding SIP, web and converged application servers, whether commercial, open source or independently developed. Applications paired with PowerMedia XMS scale efficiently on common datacenter infrastructure with high availability to meet accelerating subscriber demand. XMS can be deployed in private and service provider datacenters, or in traditional environments such as Next Generation VoIP networks or the IP Multimedia Subsystem (IMS) as a Media Resource Function (MRF). TDM network deployments are supported as well, through VoIP gateway connectivity. A software based IP communications product built on a robust, feature-rich, and award-winning host media processing engine, PowerMedia XMS can help reduce development and operational costs via flexible development and runtime licensing options. The simple, flexible, and scalable licensing model of PowerMedia XMS lets customers pay only for the functionality they need when they need it. 2

Deployment Environments PowerMedia XMS can be deployed on premise, in private and public datacenters, and in service provider networks, allowing deployment flexibility for enterprise and service provider solutions. Support for VMWare KVM, Xen Server and Oracle VM virtualization means that XMS can be installed on a virtual machine image and is ready for application control within distributed cloud environments. The control interfaces offered with XMS provide developers with the following choices of deployment environments: Traditional VoIP / IMS and LTE Network Deployments A SIP Application Server (AS) controls XMS using the MSML control interface (RFC 5707) to enable deployment as an IP media server or IMS Media Resource Function (MRF). Additionally, SIP developers can choose to use the NetAnn interface (RFC 4240) to provide basic network media services over SIP, such as network announcements, basic conferences, or VXML dialogs. The PowerMedia XMS VoiceXML 2.0/2.1 compliant interface can be used to interpret VXML scripts and create voice-enabled applications that utilize MRCP-enabled speech servers for Automatic Speech Recognition (ASR) and Text to Speech (TTS) capabilities. In all of these examples, PowerMedia XMS can also handle SIP calls with WebRTC media, DTLS-SRTP security, and NAT traversal via ICE that originate from WebRTC-enabled browsers. J2EE Converged Application Server Deployments A converged application server handles both web applications (HTTP) and SIP services using SIP Servlets (JSR 289). An application deployed on a J2EE Converged Application Server can use the JSR 309 connector software for PowerMedia XMS (licensed from Dialogic) to enable XMS as an external media server resource. Dialogic s JSR 309 connector software enables a J2EE Converged Application Server access to the real-time communications capabilities of PowerMedia XMS through JSR 309 compliant API calls. The Dialogic JSR 309 Connector also supports multimedia applications with WebRTC media. Next-Generation IP and Web 2.0 Deployments A web application written in an appropriate language (Python, JavaScript, etc.) can control XMS using the HTTP RESTful interface. Developers can use call processing functionality built into XMS or use a third-party call control model where SIP or WebRTC signaling is handled by an Application Server. The XMS RESTful API offers web-centric HTTP control of media services for WebRTC applications. Figure 3 shows an example of a typical deployment of PowerMedia XMS in a Java EE environment. This type of solution can be used for delivering media-rich services such as IVR, conferencing and announcements, as well as in call center applications. In the depicted environment, the J2EE server capabilities can be leveraged to provide application redundancy and high availability for enterprise or service provider applications. J2EE Application Servers and media resources may be geographically distributed, allowing remote access for operation and management.
